Fiber laser cutting machine is a newly emerging laser cutting method which is professionally suitable for sheet metals cutting. Before buying such a powerful machine, 3 questions should be considered to ensure the practicability and performance of the machine.
1. Why different auxiliary gases are used to cut stainless steel and carbon steel?
Customers who are familiar with fiber laser metal cutting machine know that different auxiliary gases are utilized to cut different metal types – nitrogen is used to cut stainless steel and oxygen is used to cut carbon steel. But most of them may have no clear ideas about the reason.
This mainly results from the different component content in the metals. Due to that there is less carbon content together with some rare metal content like chrome, nickel, molybdenum in stainless steel, nitrogen is enough to assist finishing the cutting process. While carbon steel has a high quantity of carbon content, which needs oxygen to give a combustion-supporting power to achieve better cutting results.
2. How to set up the cutting parameters when processing galvanized sheet?
Many customers buy fiber laser cutters to process galvanized sheet which has two different cutting situations. For those 1-2mm galvanized sheets, the cutting parameters and auxiliary gases are the same with that of stainless steel. And as for cutting over 2mm galvanized sheet, the cutting parameters should be referred to carbon steel. Hence users have to adjust cutting parameters to process galvanized sheet with different thickness.
3. If I want to cut hyper-reflective metals, how should I choose the fiber laser cutter?
During cutting the hyper-reflective metal, it will reflect the laser beams back to the laser head via the optical path, causing great damage to the fiber laser generator. Common hyper-reflective metals consist of aluminum, brass, red copper, etc, which requires users to choose professional fiber laser cutting machine manufacturers whose machines are equipped with high quality laser generator and strict quality guarantee.
As a senior fiber laser cutting machine manufacturer, we provide 3 years warranty for the whole machine body and 2 years for the laser generator for customers. Meantime, our machines adopt American nLIGHT laser generator, a famous fiber laser brand with specified quality guarantee, to process hyper-reflective metals. Customers won’t worry about the quality and after-sales service of our fiber laser cutting machines. And welcome to your personally visiting our factory to test and choose machines from a wide range of models.
